General Information
      The Official Sea-Monkey® Handbook describes Sea-Monkeys® as a variety of Artemia, which are crustaceans, such as Brine Shrimp or Seed Shrimps. Their correct Latin name is "Artemia nyos" after the New York Ocean Science Laboratories where the hybrid Sea-Monkeys were developed. Called Sea Monkeys because of their tails, they are actually brine shrimp that have been "locked away in time" through a process of "cryptobiosis" -- a reversible state in which an animal's metabolism has come to a virtual standstill. This is a natural occurrence in which some crustaceans are able to seal themselves away in their eggs until they are ready to be born. Sold in packages, their tiny Sea-Monkey eggs are enclosed in little crystals which hold them in a state of suspended animation for as long as several years, until they are placed in water, and the eggs hatch.

                                                                                                                                  Sea-Monkeys are often exaggerated on the packages in which they are sold. Transcience corporation advertises Sea-Monkeys as human-like creatures with tails and gills. As you can see to the left Sea Monkeys look much different as they are advertised.


Sea-Monkeys have no specific mating time. Sea-Monkeys may mate more than once. When Sea-Monkeys mate they stick together for many days. The female Sea-Monkey looks different from the male, the male Sea-Monkey has a cress around its neck and a female lacks this cress. Once the female has mated it will carry an egg sack on its stomach. It is advised not to disturb sea-monkeys while they carry this sac. There is also a product to make Sea-Monkeys mate this product is available on the official Sea-Monkey webpage.

  In the Sea-Monkey Ocean Zoo® is every thing you need to start your Sea-Monkey experience:
Water purifier
Instant Live Eggs
Growth Food

When the water level gets low, should I add more Water Purifier?No, just fill to the correct level with distilled or purified water. The Water Purifier is designed as a one-time formula
Can I use tap water?Nope. Distilled or filtered water is best.
Why do I have to add Water Purifier before adding the Instant Life eggs? The Water Purifier is a Top Secret combination of buffers and special ingredients that help Sea-Monkeys hatch and thrive. The actual composition is and known only by Mr. Von Braunhut (the creator) and a few others.
Do I ever need to add salt to their water?No, everything they need is in their Instant Life packet.
Why is the water cloudy?You're probably feeding your Sea-Monkeys too much. Temporarily discontinue feeding until the water begins to clear. Don't worry, there's plenty of food and algae for your Sea-Monkeys to thrive on!
Do Sea-Monkeys like the sun? Should I put them in sunlight to stay warm? Sea-Monkeys are photo-reactive (meaning that they will react to sunlight), and they love the sun. Indirect sunlight is okay but keep them out of direct sunlight, so that their tank doesn't get too hot!
What temperature should the water be? Room temperatures around 72° F (22° c) should be fine.
Can I color my Sea-Monkeys by adding food coloring to the water?Uh, no. Adding anything to your tank not specifically designed by Transcience Corp for Sea-Monkeys will probably kill them.
Should I change the water periodically?Nope.

How often should I feed my Sea-Monkeys?The Official Sea-Monkey Handbook suggests feeding them once a week using the small end of your feeding spoon. If you have a large colony, you may feed them more often, but remember if the water gets cloudy you're feeding them too much.
I heard that I can feed them yeast instead of Growth Food, is this true?Only if you really want all of your Sea-Monkeys to die.
I'm running out of food, is there something else that I can feed them? -- How about fish food? Absolutely not, your pets cannot survive on anything other than Sea-Monkey food. You can purchase food packets and more from our online store.
Is the Growth Food supposed to be green, or is it moldy?Yes it is. And no it isn't.
Does Growth Food taste good? Only to the Sea-Monkeys, but there's no accounting for taste!

My Sea-Monkeys are stuck together, what's happening? Try not to blush but your Sea-Monkeys are mating! Pretty soon new Sea-Monkey babies will be on the way.
How does Sea-Monkeys reproduce?The male and female can mate together sexually or the female can fertilize her own eggs, a process called parthenogenesis or "self-conception"!
How can I tell if I have any pregnant Sea-Monkeys?The female will carry an egg sac near her stomach.
What happens if the pregnant female dies before releasing her eggs?To insure the survival of the species, nature sometimes causes the female to release her eggs, even after death.
How many babies do Sea-Monkeys have?They usually have about 20 offspring at a time.
How long after mating will it be until the babies are born?Not even we know for sure.
How long does mating take?Sometimes you may see your Sea-Monkeys attached for several weeks, so try to give them some privacy.
Do Sea-Monkeys get hurt while mating?Not usually, although sometimes things can get pretty rough.
What are those sacs hanging off my Sea-Monkey? Are they Sea-Monkey testicles?Uh No, actually, those are the females' egg sacs.
I'm worried that there are too many Sea-Monkeys in the tank. How many is too many? Your tank will safely hold about 100 Sea-Monkeys, more than that and there may not be enough oxygen for all of them.
The babies are swimming to the surface of the tank a lot, is this ok?They're supposed to. Baby Sea-Monkeys require more oxygen and are surfacing to get it. Baby turtles and dolphins do the same thing!


My tank has lots of gunk on the bottom, how do I clean it?That gunk contains Sea-Monkey eggs and algae. You don't need to clean it, but if you wish you can just suck up some of that gunk with your Aqua Leash. Don't forget to top off the tank with more water!
Should I remove the Sea-Monkey shells after they shed them?It's not necessary, all of the stuff that collects on the bottom of the tank are part of the Sea-Monkey ecosystem.
I have a film of blue-green algae in my tank, should I clean it?This is algae and normally occurs if you keep your tank near a bright light source. It's very beneficial to your Sea-Monkeys, like a jumbo salad for them. But you can use the Aqua Leash to clean the tank if you wish.
Should I change the water periodically?No. Add clean, fresh water to recommended levels as it evaporates. There is no need to change the water.
How do I order more Sea-Monkey supplies?You can purchase them through our on-line store, or purchase them through mail from Transcience Corporation: P.O. Box 809 Bryans Road, MD 20616
Can I contact Transcience via email?Not at this time.

I accidentally ate the contents of one of the packets, should I seek medical attention? No, but what were you thinking? While not very tasty to humans, all of the packets (Water Purifier, Instant Life, Growth Food, etc.) are completely non-toxic. The only exception would be if you had some sort of allergic reaction.
I accidentally poured the whole Growth Food packet into the tank, what do I do?!
  • Move quickly! As long as your Sea-Monkeys are alive you still have hope.
  • Find a clean jar to transfer your Sea-Monkeys into.
  • Using your Aqua Leash extract water from the center of the tank (since the surface of the water will have food floating on it) and transfer to the new jar.
  • Using your Aqua Leash, transport as many of your Sea-Monkeys as possible.
  • Place a clean white paper towel, or paper coffee filter over another clean jar.
  • Pour the remaining water from your Sea-Monkey tank through the filter. This will filter your water, but will unfortunately filter out any extra Sea-Monkey eggs you may have had.
  • Rinse your Sea-Monkey tank with clear water.
  • Pour your filtered water back into your Sea-Monkey tank
  • Pour your live Sea-Monkeys back into the Sea-Monkey tank.
  • Cross your fingers!
My Sea-Monkeys are dying! What do I do?
The Sea-Monkeys life cycle varies, and so will see the number of pets in your tank. However, it is possible that there could be a real problem.
  1. Have you fed them once a week with the small end of the feeding spoon?
  2. Is the water cloudy? It's possible you've overfed them. Wait until the water clears and try again.
  3. Is the water too warm? The temperature should be around 72* F.
  4. Are they getting enough oxygen? Be sure to aerate several times a week
